This is an extremely early test of the new interactive
HTML John Muir Trail Map. Try and see if it works...
I'll make the passes clickable soon, and add more visual features, including
trail highlights and visible trail segments. This newer version of the
map is far more accurate than the last one, which is the main reason I
created it. I lifted the trail straight from TOPO
and fiddled about with it in Photoshop.
